Although he’s still known as small-screen sweetheart Jim Halpert on The Office, John Krasinski‘s also been building up his film resume with about a dozen films in the past five years. Most of them have landed on the lighter end of the comedy-drama spectrum, but his starring turn in the Sundance indie Nobody Walks sees him traveling into somewhat heavier territory.

Krasinski and Rosemarie DeWitt play a married couple whose lives are disrupted when a beautiful acquaintance named Martine (Olivia Thirlby) comes to stay with them in LA. Krasinski’s character soon finds himself irresistibly drawn to her, as his wife and teenage stepdaughter (India Ennenga) are dealing with illicit longings and impulses of their own. Nobody Walks is the third feature directed by Ry Russo-Young, who seems to be moving away from her mumblecore roots with this polished picture. Watch the trailer after the jump.
